There are many useful exporters, which could be very useful.
Currently it looks like this options is hardcoded, but this need to be changed:
Potentially we have a 3 sources for this value:
Default list with basic exporter, could have different values for lxd and physical host.
Relations, some charms could request to enable custom exporters for them, for example ntp charm
And the last one is charm config, For things like bcache statistics and conntrrack it is hard to identify if such exporters are actually needed so manual override would be helpful
Obviously each exporter should has corresponding list of alerts, but this is something for the future.
For now it would be cool to make it configurable, so we could enable collectors manually and add custom rules through cos-configurator.
